Data migration taxes migration time budgets
It can take months to move data from one platform to another. Just ask Bradley Rish, who as part of the Potpourri Group managed a two-step process to migrate away from Ecometry software on an N-Class HP 3000. Potpourri first went to Ecometry on HP-UX, then a few years later moved away from HP's proprietary environment to Windows. Same application, with each move aimed at a more commodity platform.
But there was nothing commodity about the company's data. Data migration required eight months, more than the IT pros at the company estimated. Rish said that two full-time staffers, working the equivalent of one year each, were need to complete the ultimate migration to Windows.
Migrations of data don't automatically mean there's an exit from the HP 3000. At Potpourri, after a couple of years of research by IT, the exit from the 3000 was based on HP's plans for the computer, not any inability to serve more than 200-plus in-house users, plus process Web transactions. It's a holding company that serves 11 other web and catalog brands. Starting now through the end of 2015, more than half its transactions occur in the final 90 days of each year. Holiday gift season is the freeze-out time for retailer IT changes.
High-transaction installations create some of the largest collections of data. Two staffers working for one year is one approach to leaving an app. For the record, by the second migration, Ecometry still wasn't working as fast as it did on the 3000. But sometimes vendor plans for a server demand a migration. "Ecometry is IO unfriendly under Oracle," said Rish, "but Ecometry is less unfriendly under Windows than HP-UX. It's still not as fast as the 3000."
If the speed of processing takes a hit, at least there's a way to complete a migration quicker. Automation slims down the time required to move data. Some details on how this works, and reports of success in the field, will come from MB Foster on the Wednesday Webinar, starting at 2 PM Eastern Time.Potpourri operates some familiar websites, but CEO Birket Foster's company has even better known case studies to share. Exxon, for example, "had a very customized application running on an HP 3000," he said, "and we moved it to an HP Itanium Unix box. There are Endian issues in doing that," referring to the differences between Big Endian and Little Endian data types of HP 3000s and HP's Unix systems." The company had an operation of 300 well-heads.
"You can't buy a 300 well-head off the shelf application anywhere," he said in a Webinar earlier this year. "It was a $32 billion a year operation, and we were able to complete it for them under budget, and on time." UDACentral was at the heart of that project.
MB Foster recently began to license that software for use by independent integrators and consultants. Rental licensing is new, based on project size in records, as well as duration of use. Two years elapsed between those Potpourri migrations from Itanium to the Ecometry that runs on Intel Dell servers. In the retail business, getting a project completed in nine months is crucial. That holiday quarter is off limits for changes.
